Description: Fig-3 shows the Evolutionary diagram of the Chile Ridge Movement. The magmatism of under Taitao Peninsula from about 6 Ma to 5.7–5.1 Ma is shown. CTJ stands for Chile Tripple Junction. A) The ridge is located at the edge of the Chile Trench. the Magma chambers developed and cause the upwelling of the ophiolite onto the surface of the spreading ridge. Cabo Raper pluton is also shown in the diagram. B) The old magma chamber is pushed away by the new magma chamber. Some ophiolite was also formed when the Nazca plate obducted and uplift. A new magma chamber was generated. The Chile Ridge segment subducts beneath the South American Plate.
